What E2 means on a Kenmore dryer

The E2 error code on a Kenmore dryer indicates that the control board has detected a shorted circuit in the thermistor. The thermistor is a temperature-sensing resistor whose resistance changes predictably with temperature. Under normal operation, the thermistor sends a variable resistance signal to the control board, allowing the dryer to regulate heat output accurately. When the circuit shorts, the resistance drops to near zero ohms, which the control board interprets as an impossibly high temperature reading or a sensor failure, triggering the E2 fault.

A shorted thermistor circuit can result from direct failure of the thermistor component itself, damaged wiring in the thermistor harness, or a connector that has corroded or melted and created an unintended electrical path. Heat exposure over time is a common contributing factor, as the thermistor is located in a high-temperature airflow path inside the dryer. Moisture intrusion, lint buildup around wiring, or physical damage to the sensor leads can also produce a short condition.

The recommended first step for diagnosing E2 is performing the thermistor test outlined in Test #3C. This test involves checking the thermistor's resistance and verifying the integrity of the wiring harness between the thermistor and the control board. Identifying whether the fault lies in the sensor itself or in the associated wiring is critical before replacing any components, as both can produce identical fault codes.

Common causes of E2

  1. 01

    Failed thermistor (shorted internally)

    Part replacement

    The thermistor itself has shorted internally, causing its resistance to drop to near zero ohms instead of varying with temperature. This is the most frequent cause and is confirmed during Test #3C by measuring the thermistor's resistance directly.

  2. 02

    Damaged or pinched wiring harness

    Part replacement

    The wires connecting the thermistor to the control board may be pinched, frayed, or melted, creating a short between conductors. Inspect the harness routing from the thermistor to the control board for any visible damage or contact with hot surfaces.

  3. 03

    Corroded or melted connector

    Wiring / connection

    The thermistor connector can corrode or suffer heat damage, allowing the terminals to contact each other and create a short. Look for discoloration, melted plastic, or corrosion at the connector body during inspection.

  4. 04

    Lint or moisture contamination near thermistor

    Wiring / connection

    Lint accumulation or moisture around the thermistor leads can create an unintended conductive path between the sensor terminals. Cleaning the area around the thermistor and drying it out may resolve the fault in some cases.

  5. 05

    Faulty control board

    Part replacement

    If the thermistor and all associated wiring test correctly during Test #3C, the control board's thermistor input circuit may itself be faulty. This is the least common cause and should only be considered after the sensor and harness have been ruled out.

Frequently asked questions about E2

What does E2 mean on a Kenmore dryer?
E2 on a Kenmore dryer means the control board has detected a shorted circuit in the thermistor, which is the component that monitors temperature inside the dryer. When the thermistor circuit shorts, its resistance drops abnormally low and the control board cannot get a valid temperature reading. The dryer stops operation and displays E2 to alert you to this fault. A thermistor test (Test #3C) is the starting point for diagnosing the root cause.
Can I fix a Kenmore dryer E2 error myself?
A knowledgeable DIYer can diagnose and repair an E2 error by performing the thermistor resistance test and inspecting the wiring harness for damage. If the thermistor itself has failed, it is a relatively straightforward part replacement. However, if the short is located in a damaged harness or a connector that requires careful disassembly, some comfort with appliance wiring is needed before attempting the repair.
Is it safe to run my Kenmore dryer when E2 is displayed?
You should not continue operating the dryer while E2 is active. The thermistor is responsible for monitoring heat levels inside the drum, and with a shorted sensor the dryer cannot regulate temperature properly. Running the dryer in this condition risks overheating, which can damage components or create a fire hazard. The dryer should remain off until the fault is diagnosed and the sensor circuit is restored to proper function.
Will resetting the dryer clear the E2 error code?
Resetting the dryer by unplugging it or cycling the power may temporarily clear the E2 display, but the error will return quickly if the underlying short in the thermistor circuit has not been corrected. A reset alone does not repair a failed thermistor, damaged wiring, or a faulty connector. Clearing the code without addressing the cause will result in the dryer faulting out again, often immediately upon starting a cycle.
How much does it cost to repair a Kenmore dryer E2 error?
Repair costs depend on which component has failed. A replacement thermistor is generally an inexpensive part, with DIY costs typically in the range of $15 to $40 for the part alone. If the repair requires professional service, labor charges will add to that figure, bringing the total to roughly $100 to $200 depending on your area. A control board replacement, if it turns out to be the root cause, is significantly more expensive and can range from $150 to $350 or more including labor.
